Description

Technical Field

[0001] The present invention relates to the field of secondary energy utilization, and in particular to a magnetic energy-assisted low-pressure steam power generation system suitable for power generation from waste heat recovery in small-scale garbage cracking incinerators. Background Art

[0002] The traditional method for solid waste disposal is landfilling. However, practice has proven that landfilling causes significant environmental pollution. Subsequently, incineration has been found to offer a lower environmental cost. Most of the heat generated during incineration is used to crack the waste, but some of this heat is inevitably discharged with the flue gases. To utilize this heat, devices have emerged that generate electricity using the residual heat in the flue gases.

[0003] Large-scale waste incinerators typically produce flue gas at temperatures of 600-800°C. Using this flue gas to heat boilers can generate steam at a pressure of at least 2 MPa, which can then be used to generate electricity. This is entirely feasible, as exemplified by announcements CN222210332U and CN212614920U. However, for smaller waste incinerators, the flue gas temperature typically only reaches 300-400°C due to the interplay of complex factors, including equipment efficiency, waste feedstock composition, and combustion conditions. If this flue gas is used to heat boilers, the resulting steam pressure rarely exceeds 1 MPa. This low-pressure steam is difficult to drive existing steam turbines, making it difficult to use for steam power generation. Even if it were used, it would suffer from low efficiency and limited power generation. Consequently, the flue gas produced by existing small-scale waste incinerators is difficult to reuse and is typically discharged directly, resulting in energy waste. Summary of the Invention

[0008] As a further improvement of the present invention, a mounting seat is provided on the mounting platform, one end of the transmission shaft is connected to the mounting seat through a bearing, and the other end of the transmission shaft is provided with an elastic coupling, which is connected to the drive shaft.

[0010] As a further improvement of the present invention, the condensation assembly includes a pipeline condenser, the input end of the pipeline condenser is connected to the steam output pipe, and the output end of the pipeline condenser is connected to a heat exchange water tank through a steam guide pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention improves the structure of the steam turbine so that it can be driven by a relatively low steam pressure, thereby achieving the purpose of driving a generator to generate electricity. According to actual measurements, a steam pressure of 0.5 MPa is sufficient to drive the steam turbine. During use, the relatively low-pressure steam input from the steam inlet pipe drives the active impeller to rotate, thereby driving the drive shaft and transmission shaft to rotate, thereby generating electricity. After passing through the driving blades, the steam flows into the guide vanes of the conical guide impeller, and then the guide vanes guide the steam to the steam output pipe. After being guided by the guide vanes, the back pressure generated by the steam outflow can be reduced, so that the steam energy can act on the drive shaft as much as possible, thereby improving energy utilization efficiency.

[0016] The present invention can provide auxiliary driving force by arranging a magnetic booster assembly on the generator, thereby improving power generation efficiency. At the initial startup, the drive shaft of the steam turbine drives the transmission shaft to rotate, and the transmission shaft drives the mover to rotate synchronously. When the second permanent magnet moves closer to the first permanent magnet, negative work is performed. After passing the resistance point, the second permanent magnet and the first permanent magnet pass through the resistance section and rotate away from each other, so that the magnetic energy of the two permanent magnets performs positive work on the circumference, and in a circular motion, the positive work is greater than the negative work. Therefore, as the drive shaft continues to rotate, the mover will accelerate, which in turn drives the transmission shaft to rotate faster, and then drives the generator to generate electricity. The magnetic booster assembly performs external work and provides auxiliary driving force. BRIEF DESCRIPTION OF THE DRAWINGS

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to mutually exclusive, independent, or alternative embodiments to other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this disclosure may be combined with other embodiments.

[0027] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figure 1-7The figure shows a magnetic energy-assisted low-pressure steam power generation system, comprising a mounting platform 1, on which are fixedly mounted a steam turbine 2, a generator 3, and a condensing assembly. The steam turbine 2 is connected to an external boiler, which in turn is connected to the generator 3. During operation, waste heat from the flue gas generated by the waste incinerator is transferred to the boiler to heat the water in the boiler. The resulting low-pressure steam is then transported through a pipeline to the steam turbine 2, which then drives the generator 3 to generate electricity.

[0029] The steam turbine 2 includes a turbine housing 21, which is fixedly connected to the mounting platform 1 via a base. The turbine housing 21 is equipped with a steam inlet pipe 22 and a steam outlet pipe 23. The steam inlet pipe 22 is connected to an external boiler. Low-pressure steam generated by the boiler is transported through a pipeline to the steam inlet pipe 22 and then to the steam turbine 2, thereby driving the steam turbine 2. The steam outlet pipe 23 is connected to a condensing assembly, which is used to condense the steam into liquid water. During operation, low-pressure steam flows into the steam turbine 2 through the steam inlet pipe 22 to drive the steam turbine 2. After that, it flows out of the steam turbine 2 through the steam outlet pipe 23. The steam is then condensed into liquid water by the condensing assembly. The condensed liquid water can be re-extracted into the boiler, achieving water recycling and improving environmental performance.

[0030] A regulating valve 4 is installed on the steam input pipe 22. The regulating valve 4 is used to adjust the flow rate and pressure of the steam flowing into the turbine casing 21 to ensure that the energy of the steam can be fully utilized and improve the energy utilization efficiency.

[0031] A rotatable drive shaft 24 is provided in the turbine housing 21. The drive shaft 24 is fixedly connected to the turbine housing 21 through a bearing, and the drive shaft 24 can rotate in the turbine housing 21. An active impeller 25 and a conical guide impeller 26 are fixedly sleeved on the drive shaft 24. A plurality of drive blades 27 are arranged at equal intervals on the active impeller 25, and a plurality of guide blades 28 are arranged at equal intervals on the conical guide impeller 26. The guide blades 28 are arranged in a one-to-one correspondence with the drive blades 27. The conical guide impeller 26 can guide the steam on the active impeller 25 to the steam output pipe 23. During operation, the low-pressure steam in the boiler flows into the turbine casing 21 through the steam inlet pipe 22. The steam will impact the driving blades 27, thereby driving the driving blades 27 to rotate, driving the active impeller 25 and the driving shaft 24 to rotate, and then driving the generator 3 through the driving shaft 24 to generate electricity; at the same time, the driving shaft 24 will also drive the conical guide impeller 26 to rotate synchronously. After impacting the driving blades 27, the steam will flow to the guide vanes 28 as the driving blades 27 rotate, and then flow into the steam output pipe 23 as the guide vanes 28 rotate, and then flow to the condensation component to condense into liquid water.

[0032] The driving blades 27 and the guide blades 28 are arranged in a one-to-one correspondence, and the surfaces of the two are smoothly connected to the whole, so that the back pressure of the steam can be reduced after the steam is guided by the guide blades 28 on the conical guide impeller 26, thereby reducing energy loss, so that the energy of the steam can act on the drive shaft 24 as much as possible, thereby improving the energy conduction efficiency. The magnetic energy-assisted low-pressure steam power generation system can drive the steam turbine 2 to work using steam at a lower air pressure, thereby achieving power generation; according to actual measurements, the steam turbine can be driven to work when the steam pressure is 0.5MPa. It can be seen that the magnetic energy-assisted low-pressure steam power generation system can be used for heating boilers with low-temperature flue gas discharged from small-scale waste incinerators to generate electricity, thereby improving energy utilization efficiency and reducing waste.

[0033] To further improve energy efficiency, a graphene coating is applied to the surfaces of the drive blades 27 and guide vanes 28. This coating improves surface smoothness, shortens steam residence time on their surfaces, and reduces frictional losses, thereby improving steam energy efficiency. In this embodiment, the thickness of the graphene coating on the drive blades 27 and guide vanes 28 is 30-100 microns. After application of the graphene coating, the friction coefficient of the drive blades 27 and guide vanes 28 was measured to be ≤0.1.

[0034] The generator 3 includes a generator housing 31, which is fixedly connected to the mounting platform 1 through a base. A rotatable transmission shaft 32 is provided in the generator housing 31. The rotation of the transmission shaft 32 can drive the generator 3 to generate electricity. The generator 3 can adopt an existing generator 3, and its structure is not described in detail in this article. The transmission shaft 32 is connected to the drive shaft 24. During operation, the drive shaft 24 drives the transmission shaft 32 to rotate, thereby driving the generator 3 to work and generate electricity. A magnetic booster assembly 5 is installed on the generator 3, and the magnetic booster assembly 5 is used to drive the transmission shaft 32 to rotate; by driving the transmission shaft 32 to rotate together with the magnetic booster assembly 5, the power generation efficiency of the magnetic energy boost low-pressure steam power generation system can be improved.

[0035] Specifically, the magnetic thrust assist assembly 5 includes a stator 51 and a mover 52. The stator 51 is fixedly mounted on the generator housing 31, and the mover 52 is sleeved on the drive shaft 32 and fixedly connected to the drive shaft 32, and can rotate synchronously with the drive shaft 32; the stator 51 is sleeved on the periphery of the mover 52, and the stator 51 and the mover 52 are gap-fitted; the stator 51 is provided with a plurality of first permanent magnets 53 in a circular array, and the mover 52 is provided with a plurality of second permanent magnets 54 in a circular array, and the polarity of the ends of the first permanent magnet 53 and the second permanent magnet 54 that are close to each other are the same. When the magnetic energy boosts the low-pressure steam power generation system, at the initial startup, the drive shaft 24 of the steam turbine 2 drives the transmission shaft 32 to rotate, and the transmission shaft 32 drives the mover 52 to rotate synchronously, and when the second permanent magnet 54 moves closer to the first permanent magnet 53, negative work is done; after passing the resistance point, the second permanent magnet 54 and the first permanent magnet 53 pass through the resistance section and rotate away from each other, so that the magnetic energy of the two permanent magnets does positive work on the circumference, and in a circular motion, the positive work is greater than the negative work; therefore, as the drive shaft 24 continues to rotate, the mover 52 will accelerate, which in turn drives the transmission shaft 32 to rotate faster, driving the generator 3 to generate electricity, that is, the magnetic boost component 5 does work externally and provides auxiliary driving force.

[0036] The magnetic energy-assisted low-pressure steam power generation system drives the transmission shaft 32 to rotate through the two driving forces of the steam turbine 2 and the magnetic booster assembly 5 to drive the generator 3 to generate electricity, which can improve the energy conversion efficiency and thus improve the power generation efficiency. According to actual measurements, its energy conversion efficiency can exceed 82%. The magnetic energy-assisted low-pressure steam power generation system is driven by the steam turbine 2 and the magnetic booster assembly 5 at the same time. The two interact and compensate each other, thereby ensuring the high stability of the rotation speed of the generator 3 during operation, which significantly improves the efficiency of the waste heat recovery power generation system of the small-scale waste incinerator, making its power generation capacity higher than that of the high-pressure steam turbine, effectively overcoming the problems of insufficient power generation capacity and high power generation costs faced by traditional small-scale incinerators, significantly reducing operating costs, and further highlighting the flexibility and economic advantages of small-scale incinerators in application.

[0037] In this embodiment, there are two magnetic booster assemblies 5, and the two magnetic booster assemblies 5 are symmetrically distributed on both sides of the generator 3. The provision of two magnetic booster assemblies 5 can further improve the efficiency of power generation. In other embodiments, the number of magnetic booster assemblies 5 can also be any other number.

[0038] Mounting platform 1 is provided with a mounting base 6. One end of a transmission shaft 32 is rotatably connected to mounting base 6 via a bearing. Mounting base 6 limits the position of transmission shaft 32. An elastic coupling 7 is provided on the end of transmission shaft 32 away from mounting base 6. This elastic coupling 7 is fixedly connected to drive shaft 24. The elastic coupling 7 allows a certain degree of speed tolerance between drive shaft 24 and transmission shaft 32, and allows for a certain degree of deviation between their axes. The use of the elastic coupling 7 reduces the assembly difficulty of the magnetic energy-assisted low-pressure steam power generation system, improves assembly efficiency, and reduces the risk of later failures.

[0039] During operation, when the steam enthalpy output by the boiler is ≥150 kJ / kg, the drive shaft 24 on the steam turbine 2 drives the transmission shaft 32 to generate electricity. When the steam parameters fall below a critical value, the magnetic booster assembly 5 automatically compensates for the coupling mode, achieving torque compensation. The two are matched to a ±5% speed tolerance via an elastic coupling 7, ensuring that the output power remains stable within 95%-105% of the rated value.

[0040] The lower end of the installation platform 1 is equipped with multiple support frames 8, which facilitate the stable placement of the magnetic energy-assisted low-pressure steam power generation system on the ground or at a predetermined installation location. An access staircase 9 is provided on the installation platform 1, extending to the lower end of the support frames 8. The provision of the access staircase 9 makes it easier for maintenance personnel to climb onto the installation platform 1 for work, improving the convenience of maintenance.

[0041] The condensation assembly includes a pipeline condenser 10, the input end of which is connected to a steam output pipe 23, and the output end of which is connected to a heat exchange water tank 12 via a steam guide pipe 11. During operation, steam used by the steam turbine 2 flows out of the pipeline condenser 10 through the steam output pipe 23 and into the pipeline condenser 10. The steam is condensed into liquid water within the pipeline condenser 10, and the liquid water then flows through a pipeline into the heat exchange water tank 12 for cooling, thereby condensing the steam into liquid water for subsequent reuse.

[0042] In this embodiment, a water outlet pipe 13 is provided on the heat exchange water tank 12, located below the steam draft tube 11. A water pump 14 is provided on the mounting platform 1, with its input connected to the water outlet pipe 13 and its output connected to an external boiler. During operation, water pump 14 pumps water from the heat exchange water tank 12 into the boiler, where it is then heated by flue gas from the waste incinerator, vaporizing the liquid water into low-pressure steam. This steam is then re-injected into the steam turbine 2 via the steam inlet pipe 22 to generate power. This magnetic energy-assisted low-pressure steam power generation system enables the recycling of water resources, reduces waste, and improves environmental performance.

[0043] During the actual operation process, water loss is inevitable. In order to ensure that sufficient water can be added to the boiler, a water supply pipe 15 is provided on the heat exchange tank 12. The water supply pipe 15 is located above the water outlet pipe 13. The water supply pipe 15 is used to connect to an external water source. When the water in the heat exchange tank 12 is insufficient, the external water source can inject water into the heat exchange tank 12 through the water supply pipe 15, thereby ensuring that there is sufficient water in the heat exchange tank 12.

[0044] Working principle:

[0045] During operation, the waste heat from the flue gas generated by the waste incinerator heats the boiler, causing the water in the boiler to vaporize into steam. The low-pressure steam then flows into the steam turbine 2 through the steam inlet pipe 22. The steam impacts the drive blades 27, driving the drive blades 27 to rotate, driving the active impeller 25 and the drive shaft 24 to rotate, and then drives the transmission shaft 32 to rotate through the drive shaft 24, which drives the generator 3 to generate electricity. At the same time, the drive shaft 24 also drives the conical guide impeller 26 to rotate synchronously. After impacting the drive blades 27, the steam flows to the guide vanes 28 as the drive blades 27 rotate, and then flows into the steam outlet pipe 23 as the guide vanes 28 rotate. Then, it flows into the pipeline condenser 10 to condense into liquid water, which then flows through the pipeline into the heat exchange water tank 12 for reuse.

[0046] At the initial start-up of the equipment, the drive shaft 24 drives the transmission shaft 32 to rotate, and the transmission shaft 32 drives the mover 52 to rotate synchronously, and when the second permanent magnet 54 moves closer to the first permanent magnet 53, negative work is done; after passing the resistance point, the second permanent magnet 54 and the first permanent magnet 53 pass through the resistance section and rotate away from each other, so that the magnetic energy of the two permanent magnets does positive work on the circumference, and in a circular motion, the positive work is greater than the negative work; therefore, as the drive shaft 24 continues to rotate, the mover 52 will accelerate, which in turn drives the transmission shaft 32 to accelerate rotation, driving the generator 3 to generate electricity, that is, the magnetic booster component 5 does work externally, provides auxiliary driving force, and improves the power generation efficiency of the generator 3.
